In a deregulated Var market,market power issue is more serious than in an energy market since reactive power cannot be transmitted over long distances.This letter designs a multi-timescale Var market framework,where market power that may arise in the hourly-ahead Var support service market due to system configuration deficiency and market structure flaws can be eliminated by day-ahead contract-based Var reserve service market.Settlement of day-ahead Var reserve contract is formulated as a two-stage robust optimization(TSRO)model considering worst case of uncertainty realization and potential market power that may arise in hourly-ahead market.TSRO with integer recourses is then solved by a new column and constraint generation algorithm.Results show a robust Var reserve contract can fully eliminate market power,and prevent suppliers from manipulating market prices.
